Fawaz Abdullah Alhamdi Ph.D. Research Scholar Dept.of Library & Information Science Dr. Babasaheb Ambedkar Marathwada University, Aurangabad. (MS) India Abstract - The present study attempts on the Scientometric analysis of articles on Presbyopia in Medline Database during The present study is based on 3356 references appended to 123 articles contributed on MEDLINE DATABASE. The findings revealed various aspects of the characteristics and patterns of contributions of the study. Keywords: Scientometric; Medline Database; Presbyopia Introduction: Scientometric is one of the most important measures for the assessment of scientific productions. Macias-Chapula argues that "Scientometric indicators have become essential to the scientific community to estimate the state-of-the-art of a given topic" (quoted In Lolis et. al. 2009). Scientometric is related to and has overlapping interests with Bibliometric and Informetric. The terms Bibliometric, Scientometric, and Informetric refer to component fields related to the study of the dynamics of disciplines as reflected in the production of their literature (Hood & Wilson, 2001). Review of Literature: Bala and Singh (2014) analyzed 316 scholarly communications published in the Indian journal of biochemistry & bio-physics. The analysis cover mainly the number of articles from documents cited, and most cited journals etc. study revealed that single author contributed 18 (5.7%), while the rest of 162 (51.3%) articles were contributed by multi-authors. the contributions in this journal from India are slightly more than those from the other countries. Khaparde & Pawar (2013) studied the authorship pattern and author s collaborative research in Information Technology with a sample of articles collect from LISA during The average number of authors per article is In the study the degree of collaboration (C) during the overall 10 years ( ) is 0.71 but the year wise degree of 123 P a g e

2 collaboration is almost same in all the years of mean value According to 10 years of period, the multi- authorship articles are higher and predominant on single authorship. The study found that the researches in Information Technology are keep toward team research or group research rather than solo research. Khaparde V S (2013) the paper studied the Bibliometric Analysis of Research Publication of Department of Chemistry, Dr. Babasaheb Ambedkar Marathwada University, from 1975 to It analyzed all the 774research publications from the 144 journals. It examines yearwise distribution of papers, authorship pattern, journal in which author publish, it revealed that the number of publications has increased consistently from the year 1975 to the year % of the total publications have been made in 2009, 2010, and And the majority of the publications are made with 4 authors. And also the majority of the research paper published in journal of heterocyclic chemistry. Alhamdi, Khaparde & Kanekar (2014) they attempted on bibliometric analysis of ten volumes (57-66) in the field of journal of Documentation. It is based on the references appended to International Journal of Journal of Documentation during The present study is based on references appended to 364 articles contributed by the authors in Journal of Documentation. It was found that Journals Citations are more in number than other citations. In Authorship pattern it was found that Solo Researchers are Predominant than Collaborative Researchers. The extent of collaboration was not much popular among the Journal of Documentation. The mean relative growth for articles and citation in the first five years 2001 to 2005 is reduced according to the last five years 2006 to 2010.The value of group co-efficient (gp) was only It was seen that researchers cited latest documents. Universities are the major contributors. The study shows the UK, USA, Finland, and Denmark, have the majority of most cited records in Journal of Documentation. Out of 364 articles there are 175 articles have pages length from 11 to 20. Fawaz Alhamdi and Vaishali Khaparde (2015) Analyzed Authorship pattern in cloud computing research in LISTA. They collect 108 articles during the year 2009 to 2013.In this study The number of contributions found to be the highest is 24 in the year of The rate of growth of publication highly decreased from the rate of in 2010 to0.193.in2013 Whereas the corresponding the Doubling time for different years gradually increased from 1 in 2010 to 3.95 in Ambhore and Khaparde (2014) studied 57 Open Access Online Journal on Genetics as found in DOAJ. It is observed that U.S. was in 1st rank in publishing 15 e-journals followed by U.K. English is the most common communication language for scientific community. Four e- journals on Generics also published simultaneously in English, French, Germany and Turkish languages. Based on results the study suggested that Research scholars, scientists and Professionals should browse the DOAJ site and access the free online journals on their subject areas and also suggested that scientists and Research scholars should publish their research work in online open access journals for wider visibility of their research work and for greater impact factor and citation index. Tupe and Khaparde (2016) stated in study Mapping of Physics Periodicals: A Bibliometrics Study. Total 2131 periodicals in Physics published in 50th edition of Ulrich Periodical Directory, 2012 was considered to the present study. In this study 77 Countries published 2131 Physics Periodicals. Periodicals of different continents, at the comprehensive level, the European continent stood in the first place with the highest publication 973 (45.66%) and 124 P a g e

3 other periodicals published in other five continents. The State wise distribution of periodicals 48 Periodicals Published in India. Kerala is at the top position with highest 13 (27.08%) periodicals. Khaparde V S (2013) the paper studied the Bibliometric Analysis of Research Publication of Department of Chemistry, Dr. Babasaheb Ambedkar Marathwada University, from 1975 to It analyzed all the 774 research publications from the 144 journals. It examines yearwise distribution of papers, authorship pattern, journal in which author publish, it revealed that the number of publications has increased consistently from the year 1975 to the year % of the total publications have been made in 2009, 2010, and And the majority of the publications are made with 4 authors. And also the majority of the research paper published in journal of heterocyclic chemistry. Boell, 2007 used scientometric method of analysis scientifically from academic disciplines, journals plays an important role in disseminating findings of research among the disciplinary community members. In this study he analyzed six databases focusing on LIS literature: INFODATA, Current Contents, Library and Information Science Abstracts, Library Information Science Technology Abstracts, Information Science and Technology Abstracts, and Library Literature and Information Science, and listed the core journals in areas of LIS. Journals were also ranked by the number of occurrences in multiple databases in order to identify 'core' publications. The number of journals overlapping among databases is estimated and a matrix giving the overlap is visualized using multi-dimensional scaling. In his study he prepared a comprehensive master list of 1,205 journals publishing articles of relevance to LIS. About 968 active journals were published in English, in which one third of the journals and published from the US and another one third from the UK and Germany. Nearly 16% of all journals are open access, 11% have ISIJIF, and 42% are peer reviewed. Fifteen core journals are identified and a list of the top fourteen journals published in Germany was reported. The aim of compiling a comprehensive list of LIS journal was achieved by author. Medline Database: According to MEDLINE (Medical Literature Analysis and Retrieval System Online, or MEDLARS Online) is a bibliographic database of life sciences and biomedical information. It includes bibliographic information for articles from academic journals covering medicine, nursing, pharmacy, dentistry, veterinary medicine, and health care. (Rogers, Frank B. 1964) MEDLINE also covers much of the literature in biology and biochemistry, as well as fields such as molecular evolution Compiled by the United States National Library of Medicine (NLM), MEDLINE is freely available on the Internet and searchable via PubMed and NLM's National Center for Biotechnology Information's Entrez System (Para,1& 2). Presbyopia: Presbyopia is a condition associated with aging of the eye that results in progressively worsening ability to focus clearly on close objects. Symptoms include a hard time reading small print, having to hold reading material farther away, headaches, and eyestrain. Different people will have different degrees of problems. Other types of refractive errors may exist at the same time as presbyopia. Presbyopia is a natural part of the aging process. It is due to hardening of the lens of the eye causing the eye to focus light behind rather than on the retina when looking at close objects. It is a type of refractive error along with nearsightedness, farsightedness, and astigmatism. Diagnosis is by an eye 125 P a g e

4 exam.treatment is typically with eye glasses. The eyeglasses used have higher focusing power in the lower portion of the lens. Off the shelf reading glasses may be sufficient for some (Para 1, 2 & 3). Objectives: The present study deals with the scientometric analysis of different E-journals as per the following parameters. 1. To find out the year wise distribution of contributions. 2. To analyze the authorship pattern of contributions. 3. To find out the authorship pattern of contributions (Year-Wise). 4. To examine the institution- wise distribution of contributions. 5.

Conclusion: Scientometric analysis is the major techniques of bibliometric which is used in the further study. Considering published literature present study has used quantitative method. Scientometric is relatively new subject of information. It helps to evaluate information & to handle the information in libraries and information centers by the quantitative analyzed information. It deals with the mathematical and statistical analysis. This is an umbrella term used for many studies where quantitative method or techniques are used to investigate various aspect of written document. References: 1.
